GRAIN-SEPARATOR.

Spreiliration Vorming |n|rtot'l.et1ersPatent No. 43`47S, dated .Inl l2, 1864 To all whom it muy concern.

Beit known that we, JACOB (lLUauof the town ot' Shelby, in the county' of Orleans and 'State of iew York, and GEORGE A. FISHER, ofthe town ofAlabama, in the county of Gen esce and State of New York, have invented :t new` and Improved Machine for Cleaning' or Separating` Grain and we do hereby declare the following to be a full, clear, and exact de scription ot' the Construction and operation thereof', reference being had to the accompanying drawings, making` part of this speeitica.- tion, and to the letters ot reference marked thereon..

To enable others skilled in the art tov make and use our invention, ive will proceed to describe its construction and opera tion.

Figurel is a perspective view of our machine having one. of its sides removed, so as to exhibit the internal arrangement oT" its parts. Fig. 2 is a side elevation showing the manner of connecting` and operating the meehanism. The remainingfigures are detailed views of the various parts'of'the machine shown separately.

ln all the figures similar letters indicate. cor 'responding parts.

A in Figs. l and 2 represents the case ot' the machine, which may be made ot' vany del`his case is provided .with a hopper, l, located in its upper portion, intlowhich the grain is put in the usual manf ner,-zthe hopper being provided with a roller, F, in its throat at the bottom for feeding,` out the grain, a slide, 4, forming one side t' the hopper and bein g' made adjustable, by'whieh the How of the grain is regulated. Underneath the hopper is located a series of two or more endless belts, occupying with their frames the entire width ot' the machine. These j-.belts B are mounted in frames J, the construetion ot' which is clearly shown in Figs. 3, fl, 5,

l1111117, which frames are provided with a roller,

U, at each end around -whic-h the belt B-passes,

is so located that it shall come in contact with the surface of the belt B after the latter has passed around the upper roller, C., and is returning toward the roller c at the lower end ot' the frame, as shown in Figs. l and 7. Underneath the belts are placed two inclined division or chute boards, L and L", asshown ilrFig. l. rlhe board L is placed under the lower end fot' the lower belt, B, and is inclined in the sameI direction as the belt. The other board Ll is placed under the upper end ot' said belts, and is inclined in an opposite direction.

G, Fig'. 1, represents the main shaft of the machine, from which the rollers C, D, and F are driven by means ot' pulleys andbelts, as'

shown in Fig. 2, or in any other suitable manner. By applying' a crank to the shaft G, the machine may be operated by hand 5 or, if desired, it may be driven by power in the usual manner.

The operation ot' our invention is as follows: rlhe grain to be cleaned is placed in the hopperl, from whence it is fed by the roller F onto the first or upper belt, which is adjusted at such an angle as to cause the kernels of grain to roll down the same,and from thence tall onto the lower belt, down which it also passes onto chute-board. L and is discharged Athrou fh s )ont L into a iro )er rece itaele.

l l l Thile this is being; done, the chai't' and all other material of less speeitic gravity or weight than the kernels of grain will adhere to the surface of` thebelts 4and be carried therewith up over the upper roller, C, where most of it falls down onto'the chute-board L, all that remains attached to the belt after thus passing over roller G being brushed oit by the revolving brush l) as soon as it cornes in eontact therewith, it being:r understood that the brushes D revolve in a direction opposite to that in which the under portion of the belts B move. By these means a very cheap and etticient machine is produced, by which the grain can be eii'ectually and rapidly cleaned without the use of a blast or current et' air, and by the simple application otf the well known laws `or principles ot't gravitation and adhesion.

Having thus described our invention, its construction, and operation, what we ela-iin a-s new, and desire to secure by Letters latent, is

1. Cleaning or separating grain by means of two or more endless belts, substantially as ranged to operate :is and for the purpose above shown. set forth.

2.' M ounting the bel ts insuch a manner that y they can be inclined to a. greater or less angle, IUNIIJISHER substantially in the. manner shown, when used J X 'for the purpose herein set forth. Witnesses:

'3. ln combination with the endless belts B, C. B. FAIRMAN',

. the revolving brush D, when the parts are ar- O. HEUTH.
